The jquery implementation saves the selected user

1 introduction

Functional requirements:

Select the user interface to be displayed as a pop-up box

2 page options dynamic loading (departments and users)

Save the checked user

Implementation analysis:

Save selected user logic:

Delete the previously selected list of user records (equivalent to an empty operation)
Adds a list of newly selected user records
page

  Save the Shared file

//Save the Shared file
  function shareFile(){
    //  parameter 
    var signid = chooseObj.id;
    var objtype = chooseObj.type;
    var userlist = "";
    $("input[name=shareUserId]").each(function(){
       //This is the checkbox object in that HTML. So through
       //It is ok to directly access the properties of this.checked
       if($(this).attr('checked')){
         userlist = userlist+$(this).val()+","
       }
    });
    if(userlist.length>0){
      userlist = userlist.substring(0, userlist.length-1)
    }
    $.ajax({
      url : '../share/shareFile.do',
      //url:'${ctx}/index.jsp',
      cache : false,
      type : 'post',
      dataType : 'html',
      async : false,
      contentType : "application/x-www-form-urlencoded;charset=utf-8",
      data : {
        'signid' : signid,
        'objtype' : objtype,
        'userlist':userlist
      },
      success : function(ret) {
        //Exception handling
        if(ret==3){
          handleWarm(" The target folder is itself "); 
          return;
        }else if(ret==2){
          handleWarm(" Cannot move to subdirectory "); 
          return;
        } 
        // closeflowcontent('fxcontentflow');
        refreshThisContent();
      }
    })
  }
